SNMP4J代理中的RunTimeException

我已經下載了SNMP4J，並將其添加到我的項目的構建路徑中。然後我添加了一些代碼http://shivasoft.in/blog/java/snmp/create-snmp-client-in-java-using-snmp4j/和http://shivasoft.in/blog/java/snmp/creating-snmp-agent-server-in-java-using-snmp4j/來檢查我的代理。但現在印在控制檯這些字符串：SNMP4J代理中的RunTimeException

我上傳的主人MediaFire我的洞項目： https://www.mediafire.com/?lcyap63rs93qdwo 任何人都可以解釋我，爲什麼程序拋出這些異常？我之前沒有使用過snmp，這是我在網絡課程中進行研究的第一次經歷。
